Definitions

  • the present invention provides a process for the recovery of es - sentially enantiomerically pure D-tartaric acid from a waste stream containing D-tartrate salts which comprises acidifying said waste stream to a pH of about 2.5 to 4.5 to obtain a crystalline alkali metal hydrogen D-tartrate; and reacting said alkali metal hydrogen D-tartrate. with an acid, optionally in the presence of a solvent.
  • the present invention also provides a process for the recycle of recovered D-tartaric acid in the continuous resolution of racemic 2-amino-2 , 3-dimethylbutyronitrile.
  • Imidazolinone compounds for instance, those described in U.S. 4,188,487, U.S. 4,798,619 and U.S. 5,334,576 are highly potent, broad spectrum, environmentally benign, herbicidal agents. In general, the herbicidal activity of the R-isomer is approximately 1.8 times that of the racemic imidazolinone compound.
  • Stereospe- cific processes to prepare chiral imidazolinone herbicidal agents, either directly or indirectly, from (R) 2-amino-2, 3 -dime- thylbutyronitrile are described in U.S. 4,683,324 and co-pending patent application Serial Number 09/304,401, filed an May 3, 1999.
  • Said nitrile is prepared by a two-step resolution of racemic 2 -amino-2 , 3-dimethylbutyronitrile using D- (-) tartaric acid as the resolving agent.
  • D-tartatic acid does not occur in abundance in nature, and methods for its production are limited.
  • D- tartaric acid is commercially available, it is expensive and is only available in limited quantities.
  • Imidazolinone compounds such as those described in U.S. 4,188,487, U.S. 4,798,619 and U.S. 5,334,576 are highly potent, broad spectrum, environmentally benign, herbicidal agents. Chiral imidazolinone compounds having the (R) configuration demonstrate an increase in herbicidal activity over the corresponding racemic mixture.
  • the two-step resolution described comprises a first resolution step in which racemic 2 -amino-2 , 3-dimethylbutyroni- trile (II) in C ⁇ C -alkanol is treated with D-tartaric acid (I) to afford the D-tartrate salt of (R) 2-amino-2 , 4-dimethylbutyroni- trile (III), which crystallizes from solution. Because said ami- nonitrile partially decomposes in the process of this kinetic resolution, the methanol mother liquor contains varying amounts of ammonium D-tartrate (IV) , which is ordinarily discarded.
  • This first resolution step is shown in Flow Diagram I wherein the C ⁇ -C -alkanol is methanol.
  • This second resolution step is illustrated in flow diagram II Q wherein M is an alkali metal and the water immiscible solvent is toluene.
  • D-tartaric acid is natural tartaric arid which occurs widely in nature, either as the free acid or in combination with potassium, calcium or magnesium
  • D-tartaric acid does not occur widely in nature and is commercially available only in limited quantities. Further, existing methods for producing D-tartaric acid are limited.
  • D-tartaric acid may be recovered in high yield and in essentially en- antiomerically pure form from the waste streams produced in the resolution of racemic 2-amino- 2, 3-dimethylbutyronitrile.
  • the recovered D-tartaric acid may be recycled for use in the same resolution of said aminonitrile.
  • the processes of this invention may be run repetitively, i.e., D-tartaric acid may be repeatedly recovered and recycled in a continu- ous resolution of racemic 2-amino-2 , 3-dimethylbutyronitrile, allowing for a sustainable resolution process.
  • the di (alkali metal) D-tartrate or ammonium D-tartrate waste streams produced in the resolution of the above-said aminonitrile are acidified to a pH of about 2.5 to 4.5, preferably 3.0 to 4.0, most preferably about 3.0.
  • the acidification is preferably conducted with hydro- chloric or sulfuric acid, to form the crystalline mono-basic hydrogen D-tartrate (VII) and said hydrogen D-tartrate is treated with at least one molar equivalent of an acid, optionally in the presence of a solvent, preferably an aliphatic alkanol, more pre- > ferably methanol or ethanol, to give essentially enantiomerically pure D-tartaric acid (I).
  • a solvent preferably an aliphatic alkanol, more pre- > ferably methanol or ethanol
  • the recovered D-tartaric acid (I) may then be utilized directly in the first resolution step by adding the recovered D-tartaric acid to a solution of racemic 2 -amino-2, 4-dimethylbutyronitrile in a water-immiscible solvent, such as toluene, to yield the corresponding D-tartrate salt (III) as shown hereinabove in flow diagram I .
  • Acids suitable for use in the process of the invention include mineral acids such as hydrogen halides, sulfuric acid, phosphoric acid, or the like, preferably hydrochloric acid or sulfuric acid.
  • Solvents suitable for use in the inventive process include polar solvents, preferably water miscible.
  • Preferable solvents include aliphatic alkanols such as methanol, ethanol, propanol, isopropa- nol, or the like, preferably methanol or ethanol, more preferably ethanol .
  • Alkali metals include sodium, potassium, or lithium, preferably sodium or postassium.
  • reaction temperatures for the inventive process are directly related to reaction rate, that is increased reaction temperature leads to increased, reaction rate.
  • exces- sively high reaction temperatures are to be avoided.
  • Suitable reaction temperatures may be about 0°C to 50°C, preferably about 5°C to 35°C, more preferably about 10°C to 30°C.
  • waste streams from a 2-step resolution of racemic 2-amino-2 , 3-dimethylbutyronitrile, combined or individually, are acidified to a pH of about 3 to form crystalline alkali metal hydrogen D-tartrate and said hydrogen D-tartrate is reacted with at least one molar equivalent of acid, preferably hydrochloric acid or sulfuric acid, optionally in the presence of a sol- vent, preferably an aliphatic alkanol, more preferably methanol or ethanol, to give the desired essentially enantiomerically pure D-tartaric acid.
  • acid preferably hydrochloric acid or sulfuric acid
  • the crystalline alkali metal hydrogen D-tartrate may be isolated using conventional means such as filtration or, alternatively, may be carried on in the inven- tive process as is or as a concentrated slurry.
  • the recovered D-tartaric acid may be isolated using conventional techniques or recycled as is or as a concentrated slurry.
  • HPLC designates high performance liquid chromatography. Unless otherwise indicated, all parts are parts by weight.
  • a mixture of aqueous disodium tartrate waste produced as described in Example 1 (438.5 g, 14.5 wt% D-tartaric acid) and a methanolic mother liqucr waste slurry of ammonium tartrate (278 g, 2.6 wt% D-tartaric acid) produced as described in U.S. 4,683,324 is acidified to a pH of about 3 with concentrated hydrochloric acid over a 30 minute period at room temperature, stirred for 25 minutes and filtered. The filtercake is washed with methanol and dried under reduced pressure to afford 73.7 g (92% recovery) of D-sodium hydrogen tartrate as an off-white solid, in >99% purity and 100% optical purity, as determined by HPLC analysis.
  • a slurry of recovered D-sodium hydrogen tartrate (20.6 g, 0.119 mol) in methanol is treated with concentrated sulfuric acid (6.1 g, 0.059 mol) at room temperature, stirred for one hour and filtered to remove inorganic salts. A portion of the filtrate is concentrated under reduced pressure to give a solution of recovered D-tartaric acid (13.6 g, 0.090 mol, 82%) in methanol. This solution is treated with a solution of racemic 2-amino-2, 3-dimethylbutyronitrile (12.4 g, 0.11 mol) in toluene, stirred for 16 hours and filtered.
  • Aqueous dipotassium tartrate waste (137.0 g, 14.7 wt% D-tartaric acid) is acidified to a pH of about 3 with concentrated hydrochloric acid over a 30 minute period at 13-28°C, stirred for about 15 minutes and filtered.
  • the filtercake is washed with methanol and dried under reduced pressure to afford 24.8 g (98% recovery) of D-potassium hydrogen tartrate, in >99% purity, as determined by HPLC analysis.
